On Change Catalog client script not working

[kartikey]

Hi Everyone,

i've created an OnChange client script on a variable set, the script should return false if the age (through DOB is more than 21 )and should not allow the submission of the record producer, but return false; is not working.

the script throws alert if age is more than 21 , but it still submits the form, i want to prevent form submission.

var dob = g_form.getValue('date_of_birth');

  // alert(dob);

   var ga=new GlideAjax('CallerDeatils');

    ga.addParam('sysparm_name','getAge');

    ga.addParam('sysparm_dob',dob);

    ga.getXML(callBackFunction);

    function callBackFunction(response){

        var answer=response.responseXML.documentElement.getAttribute('answer');

// alert(answer);

if(answer>21){

    alert(" example alert");

    //g_form.clearValue('date_of_birth');

    return false;

}

}

if i use g_form.clearValue('date_of_birth');

it works but if i select 'add'  after manually typing the date,

it throws the error but takes in the value under the variable set.

any support would be much appreciated.

Hi @kartikey,

I've tested below script as onSubmit script on the variable set as working in my instance:

So this will work for every row submitted in your MRVS separately. It will not work in this form on the catalog item.

function onSubmit() {

    if (g_scratchpad.isFormValid)
        return true;

        var dob = g_form.getValue('date_of_birth');
        alert(dob);

      var ga = new GlideAjax('CallerDeatils');
        ga.addParam('sysparm_name', 'getAge');
        ga.addParam('sysparm_dob', dob);
        ga.getXML(callBackFunction);
	    return false;

	}

        function callBackFunction(response) {
           var answer = response.responseXML.documentElement.getAttribute('answer');
               if (answer > 21) {
                g_form.addErrorMessage('test');
                return false;
            }
            var actionName = g_form.getActionName();
            g_scratchpad.isFormValid = true;
            g_form.submit(actionName);
        }

perfect! Works like a charm! 😄
but i observed that we need to click 'add' twice in order to add the date of birth variable , not sure why.

Hi @kartikey, as per my knowledge return false works only on OnSubmit client script but not on the OnChange client script. Also, the GlideAjax (async) may not work with OnSubmit client script.
